主流H.264编码器对比测试 （MSU出品）

俄罗斯的MSU Graphics & Media Lab (Video Group)出品的H.264编码器性能测试报告。测试了主流的H.264编码器的性能。从测试的结果来看，开源产品x264性能已经超过了商用编码器的性能。

参与测试的编码器有如下几种：

H.264DivX H.264Elecard H.264Intel Ivy Bridge QuickSync (GPU encoder)MainConcept H.264 (software)MainConcept H.264 (CUDA based encoder)MainConcept H.264 (OpenCL based encoder)DiscretePhotonx264Non H.264XviD (MPEG-4 ASP codec)
